1850 oliver

[LLOYD P]

My 1850 leaks oil into the transmission like a fast running faucet. I've taken it apart twice. first replaced all o-rings & gaskets, next time I replaced pump seal, no luck! Next I have a 1800 parts tractor. The hyd,s worked good when parked three years ago.
Can I take every thing form the axle to the seat of the 1800 and put it on the 1850? the only difference
I see between the two is the filter location.

Thank you very much for any help I can get..

By oil i assume you mean hydraulic fluid? Narrow down how the fluid can get in and go from there. Is there a pinhole in the pan? What about the seal behind the pump gear. Been awhile since I've had one apart but there arent a lot of places to swap fluids is there?

The rearend might bolt up, but not sure if the long shaft will work; or are you talking hydraulic covers?

Will it go down setting overnight? If it does the PTO and watch where it comes from. If the filter on your 1800 is a different place you have either an A or B series 1800. That means you have a hydraulic unit that has less capacity. If you run in single acting cylinders you will also need a special bypass valve and trying to find one may be like winning a good lottery.

Remove the rear PTO/cover assy and see where it's coming in from.Pretty common for the pans to leak.
